Scan supported frequency ranges
Select a band, review its limits and save useful hits.
Choose Scan, select a supported preset or a permitted custom range, and check its start and end frequencies. Read any displayed band advisory before starting.
Start the scan with a connected receiver. Pause or cancel using the scan controls. Retuning and sampling cover a range over time; a short or intermittent transmission can be missed.
Inspect a hit before saving it as a station or tuning to it. A stored frequency is an observation and does not prove the device or service behind it.
Keep the same antenna and comparable conditions when repeating a survey. No hits with an unverified receiver is an inconclusive result. The website has separate session, expected-emitter and baseline-report tools.
